Method of outputting content through network, and apparatus and system for performing the method

1. A system for outputting content through a network, the system comprising:

a first server configured to store content received in association with an account of a user; and

a second server configured to obtain the content from the first server, convert the content into output data, and transmit the output data to an output device,

the first server, the second server, and the output device being included in a secure network,

in response to the second server receiving a request from a mobile terminal of the user to review the content and to output the content to the output device, the second server configured to determine whether the mobile terminal is included in the secure network, and

in response to the second server determining the mobile device is not included in the secure network, the second server configured to convert the content into output data for transmitting the output data to the output device and to transmit a preview which is other than the content in entirety to the mobile terminal, the preview including at least one of a thumbnail, a summary file, a partial view, and an abstract of the content, to prevent transmission of the content to outside the secure network in response to the request from the mobile terminal.

2. The system of claim 1 , wherein the second server comprises:

a mobile relay server configured to transmit the preview of the content stored in the first server to the mobile terminal; and

a printing server configured to render the content, apply security to the rendered content, and convert the secured content into the output data.

3. The system of claim 1 , wherein, to transmit the output data to the output device, the second server

receives identification information of the output device from the mobile terminal,

determines an output device corresponding to the identification information, and

transmits the output data to the determined output device corresponding to the received identification information.

4. The system of claim 3 , wherein the output device displays the identification information of the output device on at least one of a display panel provided in the output device and a display device connected to the output device.

5. The system of claim 3 , wherein the second server converts the obtained content into the output data according to a type of the output device corresponding to the received identification information, wherein

when the received identification information is a display number, the obtained content is converted into displayable output data, and

when the received identification information is a printer number, the obtained content is converted into printable output data, and

the second server transmits the converted output data to the output device.

6. The system of claim 1 , wherein the second server receives user information from the mobile terminal and transmits the user information to the output device, and

when the user information received from the mobile terminal is authenticated, the output device outputs the output data.

7. The system of claim 6 , wherein when the mobile terminal is located within a predetermined distance of the output device, the user is authenticated via near-field communication (NFC).

8. The system of claim 1 , wherein when the second server receives a request to perform print spooling from the mobile terminal, the second server converts the content into content in a preset format and stores the content converted into the preset format as a print job, and

when the second server receives a request to print the stored print job from the mobile terminal, the second server converts the content in the preset format into the output data and transmits the output data to the output device.

9. The system of claim 1 , wherein when the second server receives, from the mobile terminal, a request to check an output result of the output data on the output device, the second server transmits to the mobile terminal a result obtained after handling the output request from a point of time when the request has been received to a preset point of time.

10. A method of outputting content through a network, the method comprising:

by a first server, receiving content in association with an account of a user;

and

by a second server, converting the content into output data and transmitting the output data to an output device,

the first server, the second server, and the output device being included in a secure network, and

by the second server:

determining whether a mobile terminal is included in the secure network, in response to the second server receiving a request to review the content from the mobile terminal and to output the content to the output device; and

converting the content into output data for transmitting the output data to the output device and transmitting, to the mobile terminal, a preview of the content, which is other than the content in entirety, the preview including at least one of a thumbnail, a summary file, a partial view, and an abstract of the content, in response to the second server determining that the mobile device is not included in the secure network, to prevent transmission of the content to outside the secure network in response to the request from the mobile terminal.

11. The method of claim 10 , wherein the transmitting of the output data to the output device comprises:

determining an output device corresponding to identification information received from the mobile terminal and

transmitting the output data to the determined output device.

12. The method of claim 11 , wherein the identification information is displayed on at least one of a display panel provided in the output device and a display device connected to the output device.

13. The method of claim 11 , wherein the transmitting of the output data to the output device comprises:

converting the content into the output data according to a type of the output device corresponding to the received identification information, wherein

when the received identification information is a display number, the content is converted into displayable output data, and

when the received identification information is a printer number, the obtained content is converted into printable output data; and

transmitting the converted output data to the output device.

14. The method of claim 10 , further comprising:

by the second server, receiving user information from the mobile terminal and transmitting the user information to the output device; and

when the user information received from the mobile terminal is authenticated, outputting the output data, wherein the outputting is performed by the output device.

15. The method of claim 14 , wherein when the mobile terminal is located within a predetermined distance from the output device, the user is authenticated via near-field communication (NFC).

16. The method of claim 10 , wherein the transmitting of the output data to the output device comprises:

when a request to perform print spooling is received from the mobile terminal, converting the content into content in a preset format and storing the content converted into the preset format as a print job; and

when a request to print the stored print job is received from the mobile terminal, converting the content in the preset format into the output data and transmitting the output data to the output device.

17. The method of claim 10 , further comprising,

by the second server, when a request to check an output result of the output data on the output device is received from the mobile terminal, transmitting to the mobile terminal a result obtained after handling the output request from a point of time when the request has been received to a preset point of time.

18. A non-transitory computer-readable recording medium having embodied thereon a program for executing the method of claim 10 in a computer.
